    Synopsis:          Moderate: openstack-neutron security, bug fix, and enhancement update
    Advisory ID:       RHSA-2014:0516-01
    Product:           Red Hat Enterprise Linux OpenStack Platform
    Advisory URL:
    Issue date:        2014-05-29
    CVE Names:         CVE-2013-6433 CVE-2014-0056 
    1. Summary:
    Updated openstack-neutron packages that fix two security issues, several
    bugs, and add various enhancements are now available for Red Hat Enterprise
    Linux OpenStack Platform 4.0.
    The Red Hat Security Response Team has rated this update as having Moderate
    security impact. Common Vulnerability Scoring System (CVSS) base scores,
    which give detailed severity ratings, are available for each vulnerability
    from the CVE links in the References section.
    2. Relevant releases/architectures:
    Red Hat Enterprise Linux OpenStack Platform 4.0 - noarch
    3. Description:
    OpenStack Networking (neutron) is a pluggable, scalable, and API-driven
    system that provisions networking services to virtual machines. Its main
    function is to manage connectivity to and from virtual machines. As of Red
    Hat Enterprise Linux OpenStack Platform 4.0, 'neutron' replaces 'quantum'
    as the core component of OpenStack Networking.
    A flaw was found in the way OpenStack Networking performed authorization
    checks on created ports. An authenticated user could potentially use this
    flaw to create ports on a router belonging to a different tenant, allowing
    unauthorized access to the network of other tenants. Note that only
    OpenStack Networking setups using plug-ins that rely on the l3-agent were
    affected. (CVE-2014-0056)
    It was discovered that the default sudo configuration provided in OpenStack
    Networking, which is specific to the openstack-neutron package shipped by
    Red Hat, did not correctly specify a configuration file for rootwrap,
    potentially allowing an unauthenticated user to escalate their privileges.
    Red Hat would like to thank the OpenStack project for reporting
    CVE-2014-0056. Upstream acknowledges Aaron Rosen from VMware as the
    original reporter of CVE-2014-0056. The CVE-2013-6433 issue was discovered
    by Kashyap Chamarthy of Red Hat.
    This update also fixes several bugs and adds enhancements. Documentation
    for these changes is available in the Technical Notes document linked to
    in the References section.
    All openstack-neutron users are advised to upgrade to these updated
    packages, which correct these issues and add these enhancements.
    4. Solution:
    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.
    This update is available via the Red Hat Network. Details on how to
    use the Red Hat Network to apply this update are available at
